This study investigated whether sleep reactivity (i.e., a propensity to experience sleep disturbances when stressed) relates to eating disorder behavioral symptoms indirectly through dysphoric mood in a sample of college students. One hundred and ninety-eight college students (51.5% female). Participants completed self-report measures of dysphoric mood, eating disorder behavioral symptoms, and sleep reactivity. Higher sleep reactivity was associated with greater binge-eating symptoms indirectly through higher dysphoric mood. Higher sleep reactivity was associated with greater purging symptoms; however, this association was not explained by dysphoric mood. Findings support the relevance of sleep reactivity to binge eating and purging and suggest that sleep reactivity relates to binge-eating symptoms indirectly through dysphoric mood. If replicated in prospective data, targeting stress-induced sleep and mood disturbances in college students may reduce risk for binge eating.
本研究调查了睡眠反应性（即在压力下经历睡眠障碍的倾向）是否通过大学生样本中的烦躁情绪间接与饮食失调行为症状相关。198名大学生（51.5%为女性）。参与者完成了关于烦躁情绪、饮食失调行为症状和睡眠反应性的自我报告测量。较高的睡眠反应性通过较高的烦躁情绪间接与更严重的暴饮暴食症状相关。较高的睡眠反应性与更严重的清除症状相关；然而，这种关联无法用烦躁情绪来解释。研究结果支持睡眠反应性与暴饮暴食和清除行为的相关性，并表明睡眠反应性通过烦躁情绪间接与暴饮暴食症状相关。如果在前瞻性数据中得到重复验证，针对大学生因压力引起的睡眠和情绪障碍可能会降低暴饮暴食的风险。
